PROBLEM TO BE SOLVED: To provide a pressure type rice cooker capable of selecting a cooked rice state that suits the preference of a user from a variety of the rice cooking menu.SOLUTION: A pressure type rice cooker includes: a pressure valve 13 that opens/closes a steam discharge hole 131 communicating the inside of a pot 10 with the inside of a lid body 11; a pressure valve opening/closing part 19 for adjusting the pressure in the pot 10 by switching the opening/closing state of the steam discharge hole 131 by the pressure valve 13; and a control part for controlling a heating device and the pressure valve opening/closing part 19, and executing a rice cooking process including a temperature increasing process and a boiling maintaining process. The control part controls the pressure valve opening/closing part 19 and decompresses the inside of the pot 10 in the boiling maintaining process, and varies a decompression rate which is a pressure reduction amount per prescribed time.SELECTED DRAWING: Figure 2 【課題】利用者の好みに合った炊き上がりを豊富な炊飯メニューから選択できる圧力式炊飯器を提供する。【解決手段】鍋１０内と蓋体１１内とを連通する蒸気排出穴１３１を開閉する圧力弁１３と、圧力弁１３による蒸気排出穴１３１の開閉状態を切り換えることにより、鍋１０内の圧力を調整する圧力弁開閉部１９と、加熱装置と圧力弁開閉部１９とを制御して、昇温工程と沸騰維持工程とを含む炊飯工程を行う制御部を備え、制御部が、沸騰維持工程において、圧力弁開閉部１９を制御して鍋１０内を減圧するとともに、時間当たりの減圧量である減圧速度を可変とする。【選択図】図２
